Viking Line secures biogas for vessels plying the Turku-Stockholm route

After increasing its use of biofuel tenfold last year, the Åland-based shipping company has now secured another year at the same level.

The biogas is used alongside LNG on the company’s newest ships, Viking Glory and Viking Grace, which operate daily between Turku and Stockholm.

“Last year, our greenhouse gas emissions on Glory and Grace were reduced by nearly 50,000 tonnes. For the first half of 2026, we have secured 50% of the biogas to cover our fuel needs, and our ambition is to maintain a high level throughout the entire year,” said Viking Line head of sustainability Dani Lindberg.

By choosing Viking Lines vessels on the Turku-Stockholm route, passenger and freight customers influence the amount of biogas used in ship operations and thereby directly contribute to further emissions reductions in the Baltic Sea. Viking Line has been developing a green shipping corridor between Turku and Stockholm in co-operation with Ports of Stockholm and the Port of Turku. The objective is for the corridor to be completely fossil-free by 2035.

“Globally, there is no lack of initiatives to create fossil-free sea lanes, but most are still in the planning stages. Our investment in biogas and energy-efficient vessels is one of the clearest and largest-scale examples of how shipping can transition in practice,” said Viking Line chief executive Marcus Risberg.

In August 2025, Viking Line announced it would increase its purchases of biofuel from 600 tonnes in 2024 to at least 3,800 tonnes.

The more than sixfold increase in the company’s commitment is part of Viking Line’s contribution to a pooling service for compliance with the European Union’s FuelEU Maritime legislation that is managed and marketed by Finland’s state-owned energy company Gasum, a Nordics-focused energy supplier.
